The consensus is that 215/45R17 will fit with some trimming of the front bumper tabs and, perhaps, the sheet metal found at 3:00 in the rear wheel well. 235/40R17 are a tad shorter but they are a wide tire for a 7" wheel. I haven't heard of anyone trying a 225/45 and there aren't many good USP tires in 225/40.
I've run 2 ( maybe 3? ) front sets of 235/40-17's on stock fronts. But... the car lost some steering speed. But more importantly, the tail of the car whips a lot with such a difference in meat.
